Embodiment Construction

[0024] It is easy to understand that, according to the technical solution of the present invention, those skilled in the art can propose multiple structural modes and implementation modes that can be replaced without changing the essence and spirit of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0025] It should be understood that self-interpretation refers to a property of information that can explain itself by itself. When we construct the coupon code, we will compile the validity period of the coupon code, the code of the coupon code, the serial number of the coupon code, the supplier identification code, the agent identification code, and the production date of the coupon code into the coupon code.

Abstract

The invention provides a construction method and device and a decryption method and device of an encrypted coupon with self-interpretability, and the construction method comprises the steps of obtaining rights and interests information and user information, and the rights and interests information comprises a coupon code serial number; converting the coupon code serial number according to a password generation rule to generate a secret key; encrypting the rights and interests information by using the secret key to generate ciphertext information; signing the ciphertext information by using the user information to generate signature information; and combining the coupon code serial number, the ciphertext information and the signature information to generate a coupon code of the card coupon. According to the invention, the coupon supplier can correctly verify the authenticity of the coupon code provided by the user only by storing the own key generation rule without storing a large amount of coupon codes and personal information, so that the problem that whether the coupon code provided by the user is true or not cannot be verified after the system loses data is solved.

Description

technical field [0001] The present invention relates to the technical field of information encryption, in particular to a construction method, a decryption method and a device for self-explanatory encrypted coupons. Background technique [0002] A coupon is an (electronic) card that contains a card number and a card code or just a string of random strings (coupon code). The codes of traditional coupons are random, and it is difficult for users to find out the real codes of coupon suppliers through exhaustive enumeration. [0003] However, the card coupon supplier is bound to store some additional information in the system, such as information about the beneficiary of the distributed coupon code. Once the coupon provider stores this personal information, it must fulfill its responsibility to protect this information and prevent personal information from being leaked. [0004] In addition, the traditional method of generating coupons is that the system randomly generates a s...
